plate glass,

glassthus producing a very superior .prodnet "in the simplestpossible manner.

In the followingflescription and. accompan'yingidrawmgs the features of my invention are set forth fully, the apparatus shown being illustrated in a simple form and with out immat er' al auxiliary parts, that its salient features may be the' more'readily comprehended. e

Referring tothe said drawings,-Figure-l shows a perspective viewof oneform of apparatus for carrying out my invent-ion. Fig. 2 is a central vertical longitudinal section through the same, the receptacle being shown full of molten glass. --Fig. 3 is a transverse vertical section of the same apparatus ad jacent an end thereof. Fig. 4 is a perspectiveof a modification. 'Flg. 5 1s a central vertical longitud nal section through the form of Fig. 4, and Fig. -6 is a View showof glass from the molten mass m the trough or tank.

Like reference characters are 'used .to-

designate views.

. Referring to Figs. 1 to 3, l is a receptacle of iron or any suitable material in the form of a shallow trough or tank somewhat longer than the plates of glass to be made. This trough is shown as rectangular butits form in horizontal section is immaterial so long as such section at difierent points does not like parts in each of the-several new" and useful I1nprove-' [The inatt'ers of novelty consist, in an impress inward the cover piston 3.

the manner of forming plates'or sheets flange vary. Said trough is preferably provided e e s eciiaa iiofLetters Batent. resented-Oct; 12,1909. Application filed December 7,1907. Seria1No.405,584.i

with suitable trunnions 2, whereby it may be.

.pivotally suspended from a 'crane or like support andlilled with molten glass by dip-' plug in a glass reservoir tank.

Fitted to slide in the trough ,1 is a. follower-cover or ipiston 3, preferably 'of iron, wh1ch conforms in shape to the inside horizontal section ofsuch trough. The said follower 3 is provided with a long slot -l, the

size of such slotbeing determined by the dimensions of the glass plates it-is desired to produce. p p

5, 5 are members arranged to engage and In the embodiment shown these members consist of adjustablerod sections 5, secure at one end to the bottom of the trough ,adj'acentits ex:

- tremities as shown at '6, and bentover at the iopposite ends 'to engage the-said cover 3. Said rod sections are united by a turnbuckle T, which may .be manipulated as will be readily apparent to force thecover piston 3 inward, or to allow the same to be withdrawn at option. While I have illustrated these rod members adjustable by'a t-urn-= buckle as the means for acting" upon the cover piston, I desire itto be clearly understood that I donot limit myself to such ads-'- aware that a wide variety vice, as I am well I of operating devices to attam the same res might beused without departing from my lllt invention in its broader aspect which contemplates the employment of any suitable device to exert pressure upon the cover piston 3.

The trough 1 is preferably provided with hooks at convenient places on its sides to enable it to be easily: engaged by a suitable device for tilting it upon its .trunnions.

In Figs. 4 and 5 I show a slight modification in the designiof pistontherefor. In this form the trough 1- is provided with an inwardly. extending l at its top and the cover piston 3 hasan upstanding flange 3" around its periphery for engagement with said inwardly extending flange 1 to form a close sliding fit therewith, and, by means of the pocket formed between the flanges 1 and 3 and end walls-of trough l, a closer fit is secured.

' It is apparent that ineither case the object is to cause the molten glass to flow outward the trough and cover crane and. by means of an actuator engaging one of the lugs or hooks '8.

place the cover plston 3 1n posit on Within I thereupon the'trough and resting "on topof the molten mass therein. Then the cover engaging devices 5, are brought into position and ad brought to a convenient position by its supjnstedagainst the cover the turnbuckles'7. v

' The trough 1 and its contents having been piston by means of porting crane, i-t is swung. upon its trunnions 2- to inverted position whereupon a sheet of the molten glass may issue from the slot 4:, as shown in Fig. 6, It will be apparent that such issuance of the glass sheet will natually result from the action of gravity and it will also be understood that such issuance may be accelerated at will by compression upon the piston cover 3', such compression being exerted by manipulation of the turn-' buckles 7, 7. As shown in Fig. 6, the edge of the glass sheet 9 formed from the body .of glass 10 Withinthe trough maybe grasped Q by a pair of tongs 11 to be manipulated. as may be necessary, but as will be seen, the sur-.

faces'of the main body of the glass sheet are not at all touched by any foreign substance -or implement during its cooling and solidify'ingperrod, and hence the original virgin luste "andbrilliancy of the glass are preserved 'tothe highest possible degree, thus producing a very superior article.

Having now described my invention, what 1 claim as new and desirezto secure by Let ters Patent is as follows -1. An apparatus for making glass comprising atrough arranged to be rotated and a .combined cover and follower therefor having a slot therein of extended length.

2. An apparatus for making glass comprising a'trough having trunnions on. its ends and a combined cover and follower therefor having an elongated slot therein, the long sides of said slot being straight and parallel.

3. An apparatus for making glass comprising a rotatable trough, a cover-piston fitted to slide Within said trough, said coverpiston having an elongated slot therein, and means forexert-ing pressure upon said coverpiston.

' 4. An apparatus for making glass eompris ing a trough having an inwardly-extending flange about its top, and a cover-piston fitted to said flange having an upstanding flange for extended engagement with said trough flange, said cover-piston also having an elongated slot therein.

, An apparatus for making glass comprisinga trough having trunnions fixed to JULES J. QUERTINMONT.
